A/R .88 Ratio:

The A/R (Area/Radius) ratio of .88 provides a balanced combination of quick spool and strong top-end power. The .88 A/R is larger than typical .63 or .70 housings, which means it flows more exhaust and supports higher horsepower levels. However, it still provides reasonable spool characteristics for street and performance applications. The .88 A/R is popular for high-performance diesel trucks and gasoline builds seeking maximum power.

80/74mm Turbine Wheel:

The 80/74mm turbine wheel features an 80mm inducer (inlet) and 74mm exducer (outlet). This large turbine wheel flows significant exhaust volume, allowing the turbo to support high horsepower levels. The turbine wheel is precision-balanced and designed to withstand extreme exhaust gas temperatures and pressures.

High-Flow Design:

The turbine housing is designed to maximize exhaust flow while minimizing backpressure. The optimized internal geometry allows exhaust gases to flow efficiently through the turbine wheel, improving turbo response and power output. The high-flow design is essential for extracting maximum performance from the S300SX3 turbo.
